Characterization of erbium-doped silicate glasses produced by sol-gel method with a drying control chemical additive has been carried out. Both of the absorption and fluorescence spectra of these samples were similar to those of erbium-doped optical fibers prepared by modified chemical vapor deposition. The homogeneous monolithic erbium-doped silicate glasses with concentrations ranging from 500 to 10000 ppm were constantly fabricated. Due to N,N-dimethyl formamide (DMF) in 2-step hydrolysis procedure, the processing time can be reduced significantly. The index of refraction and specific density of the samples were approximately 1.65 and 2.2 g/cm3, respectively.
